Embodiment Construction

[0085] In scenarios such as factory wireless sensing, video surveillance, and wearable devices, the general design goals for low-capacity NR terminals include: 1. To meet the transmission rate requirements of the scenario, where the transmission rate requirements range from several megabytes to tens of megabytes to over 100M; 2. Reduce the cost and complexity of the terminal; 3. Support compact terminal size. At present, the achievement of the above general design goals is mainly considered through the following means:

[0086] 1. Reduce the maximum bandwidth supported by the terminal. The 5G system defines the system bandwidth supported by the terminal from the perspective of the frequency band. For example, the terminal needs to support the system bandwidth of 100MHz or 50MHz. If the maximum bandwidth supported by the terminal is reduced, the cost and complexity of the terminal will be reduced from both radio frequency and baseband perspectives.

[0087] 2. Reduce the numb...

Abstract

The invention discloses a control channel resource configuration method and device, a base station, a terminal and a storage medium, and the method comprises the steps: transmitting first information to a first terminal; wherein the first information is used for indicating to the first terminal that the CORESET of the type0-PDCCH comprises a resource which is subjected to frequency division multiplexing with an SSB and a resource which is subjected to time division multiplexing with the SSB.

Description

technical field [0001] The present application relates to the field of wireless technology, and in particular to a method, device, base station, terminal and storage medium for configuring control channel resources. Background technique [0002] In scenarios such as factory wireless sensing, video surveillance, and wearable devices, consider reducing the terminal capabilities of low-capacity New Radio (NR, New Radio) terminals (Reduced Capability NR devices) to reduce the cost, complexity, and size of terminals . The reduction of terminal capability may affect the coverage of the base station to the terminal, and coverage compensation design is required. However, the related technology cannot realize the coverage compensation of the control channel when the maximum bandwidth of the terminal only supports 50MHz. Contents of the invention [0003] In order to solve related technical problems, embodiments of the present application provide a control channel resource configur...
